Abstract: The invention relates to a hairdressing method consisting in curling individual locks of hair after washing and during drying of the latter. To this end, a current of suctioning air (A) is channelled inside a suction tube (11) extended by a shaping element (15) ending in a neck portion (37). The current of air (A) is oriented within the tube according to xx'. According to the direction s, the shaping element (15) is brought close to a lock (40) to be treated so that the latter is taken up inside (43) the element (15). Then, according to the direction a, the axis xx' of the element (15) is tilted with respect to that yy' of the lock (40) and this element (15) is slid in the direction t so as to curve the lock (40) into a variable longitudinal position over a rim (54) of the element (15). This produces a "curlpaper" effect, giving volume and waves to the hairstyle whose characteristics can be very variable in order to obtain any hairstyling effect. This effect can be accentuated by the combined use of a force-drying element delivering a jet of hot air in the direction of the end of the shaping element (15). <IMAGE>

Abstract: A method of forming battery plates or electrodes from tetrabasic lead sulfate includes the step of adding a lead peroxide such as lead dioxide in powdered form to the tetrabasic lead sulfate for making the paste to be applied to the plate or electrode supporting grids. The addition of this lead peroxide allows forming the plates or electrodes in an electrolyte of high specific gravity, and in reduced time, with increased efficiency and reduced energy consumption. Such battery plates or electrodes may thus be formed in their final containers or jars, significantly reducing the practical problems of disposing of used forming electrolyte solution.

Abstract: A method and a device for the anaerobic digestion of organic waste material such as manure in liquid condition include bringing the waste material in an acidification space (17) with a roof (5) collecting gas generated thereby and one or more openings (6, 36) below said roof giving access from said space to a methane fermentation space (18) so that the gas below the roof (5) pushes the liquid to said latter space. A discharge of gas (8, 40) from below said roof (5) to the outside allows liquid to flow back through said openings (6, 36) into the acidification space (17). Below said roof (5) there may be a separate wall (3, 37) defining a hydrolysis space (16), into which the waste material is fed (at 2, 39) before flowing to the acidification space (17). The whole of the device or considerable parts of the walls and ducts thereof may be made of flexible gastight material so as to be easily folded or wound up for transport to the site of use as to be inflatable to sustain its operating shape by a higher than atmospheric pressure of the gas therein. The method and the device allow good digestion in a small and simple device of high capacity and low energy demand.

Abstract: An apparatus is provided for loading a head (36) onto a spinning disc and unloading the head (36) from the spinning disc so that contact between the head (36) and the disc is essentially prevented. The apparatus includes a Whitney-size head (36) jbined to the flexure of a Whitney-type suspension arm (28). A triangular-shaped ramp (44) is fixed to a face of the suspension arm (28) for engagement with a stationary cam (50). The stationary cam (50) is located along the path of movement of the head (36), suspension arm (28) and flexure. The contact between the cam (50) and ramp (44) causes movement of the head (36) relative to the disc. In the case of loading the head (36), this movement results in a desired approach of the head (36) towards the disc and enhanced loading of the head (36) onto the disc.
